RAILROAD-iFROG.

SPECIFICATION forming part of Letters Patent No. 734,132, dated July 21,1903. Application-filed May 21, 1903. Serial No. 15 8,158. (No model.)

To all whom t may concern:

Be it known that I, RAYMOND NovINGER, a citizen of the United States,residing at Centerview, in the county of Dauphin and State ofPennsylvania, have invented a certain new and usefulRailroad-Frog, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

This invention relates to railroad-frogs, the object in view being toprovide a simple, effective, and reliable frog in which the movableparts are rendered self-adjusting, the frog comprising a pair ofwing-rails which are terminally pivoted at one end and which areyieldingly held toward the point of the frog by means of a spring devicewhich is located wholly between the wing-rails whereby said springdevice is protected from injury and the operation of the wing portionsof the rails made certain and reliable. i

With the above and other objects in View, the nature of which will morefully appear as the description proceeds, Vthe invention consists in thenovel construction, combination, and arrangement of parts, ashereinafter fully described, illustrated, and claimed.

In the accompanying drawings, Figure lis plan view of a railroad-frogconstructed in accordance with the present invention, showing the springdevice partly in section. Fig. 2 is a cross-section on the line 2 2 ofFig. l. Fig. 3 is a cross-section taken adjacent to the traveler orguide-bar. x

Like reference-numerals designate corresponding parts in all ligures ofthe drawings.

Referring to the drawings, 1 designates a base-plate of suitable size,the same being adapted to rest upon and be secured permanently to theties of the road-bed. 4The point 2 of the frog is formed by the meetingextremities of the converging rail-sections 3, which arejointed andtenoned into each other, as shown at 4. Extending transversely throughthe rail-,sections 3 is aA traveler or guide-bar 5, located a suitabledistanceabove the base-plate and having its opposite end vsupported bymeans of blocks 6, which are interposed between the traveler-bar andbaseplate, as best shown in Fig. 3. The travelerbar 5 is heldstationaryand serves as a guide for the wings of the wing-rails.

7 designates the wing-rails, which are terminally pivoted at 8 to astay-bar 9, extending transversely of the track and secured tov a tie oranchored in any other convenient manner. The wing-rails 7 convergetoward the point of the frog and after extending beyond the point of thefrog they are bent .to flare outwardly in opposite directions, thereb'yforming the wings 10, which lie on opposite sides of the frog, theextremities of the wings being bent outward, as shown at 11, to insurethe proper entrance of the iianges of the wheels between the wings andthe point of the frog in a manner readily understood by those conversantwith the art to which this invention appertains.

At the points of junction of the wings 10 y with the main body portionsof the wing-rails 7 the latter are oset outwardly in oppositedirections, as shown at 12, and within said offsets l2 are securelyfastened hard-metal reinforce-blocks 13, having their inner adjacentfaces reversely beveled, the beveled faces forming continuations of andbeing exactly in alinement with the corresponding inner edges of thewings l0 and the wing-rails 7, while the vertices 14 of thereinforce-blocks liel exactly opposite each other and close to theextremity of the point of the block, as clearly illustrated in Fig. 1.

Between the'wing-rails 7 is arranged a spring device consisting lof aspring 14, arranged within a cylindrical spring box or housing 15 and atension-bolt 16. The spring box or housing 15 is bolted, as shown at 17,to the web 18 of one of the wing-rails, while the tension-bolt 16 isprovided at one end with a head or shoulder 19, which engages the end ofthe spring, said bolt passing through thespringandthespring-boxandalsothrough the web ol the opposite rail, where it isheld and made adjustable by means of a tensionnut 20. The spring deviceas a whole is located entirely between the pivoted wing-rails, and isthereby protected from injury. The

spring device exerts its tension to yieldingly hold the wings-toward thepoint of the frog, at the same time allowing either one of the wings toyield away from the point of the frog as a train passes over the same.

21 designates a pair of wing-rail checks or inforce-blocks held in saidosets and having reversely-beveled adjacent faces and oppo- 15sitely-arranged vertices, and a spring located Wholly between thepivoted wing-rails and acting to yieldingly hold the wings toward thefrog-point, substantially as described.

In testimony whereof I aix my signature zo in presence of two witnesses.

RAYMOND NOVINGER.
